I got an outsized pair of Simms w/stocking foot a year ago & only had occasion to use them three or four times so far, once in the surf at night. I lost 50 pounds over that time, but no matter; they really fit fine; I don't feel they're baggy. Since you're 6'6", get the largest you can find, I suppose. I use size 14 wading shoes, but forget the brand. They slip on easily & are snug. I think sometimes people have fitting problems. Yeah, everyone's moving away from felt soles. I like them because they grip well, but spores are a problem. They may not be good on sand anyway.
